The Short Answer: Aged garlic extract (AGE) is garlic soaked for many months until its harsh compounds turn into milder, stable ones such as S-allyl cysteine (SAC). In small trials in people with high blood pressure, 480–1,200 mg of AGE a day lowered systolic pressure by about 10–12 mmHg over 12 weeks12. It’s a modest add-on to medical care, not a replacement for blood pressure medicine3.

Kyolic Formula 100 is our top pick: it’s made by Wakunaga, whose aged garlic extract was used in those trials, and the label dose gives 1,200 mg a day. If you’d rather get garlic, CoQ10 and vitamin K2 in one softgel, Resilia combines all three.
We compared 14 garlic supplements on garlic type and dose, stated SAC, other ingredients, safety flags, cost per day and buyer feedback. Every product is ranked by its BFN Score, a relative score within this guide. See our review process for how we score.
Aged Garlic Benefits: What the Research Shows
Raw garlic gets its smell from allicin, which forms when a clove is crushed and breaks down quickly. Aging garlic in water and alcohol for up to 20 months turns it into water-soluble compounds such as SAC, which are stable and don’t smell12. Most clinical trials on aged garlic used Kyolic extract.
- Blood pressure: In a 12-week trial of 79 people with uncontrolled high blood pressure, 480 mg of AGE a day (1.2 mg SAC) lowered systolic pressure by about 11.8 mmHg more than placebo; 960 mg worked less well, partly because fewer people stuck with it1. A 2018 trial of 49 people found that 1.2 g a day lowered systolic pressure by about 10 mmHg and diastolic by about 5 mmHg compared with placebo2.
- The bigger picture: A Cochrane review found that garlic may lower blood pressure by about 10–12 mmHg systolic, but the trials were small and couldn’t show fewer heart attacks or strokes3. NCCIH says evidence for blood pressure is limited, and garlic may slightly lower total and LDL cholesterol4.
- Artery plaque: In a one-year study of 55 adults with metabolic syndrome, 2,400 mg of AGE a day slowed the buildup of soft plaque in the heart’s arteries, measured by CT scans5.
- Colds and flu: In a 90-day trial in healthy adults, AGE didn’t reduce how often people caught colds, but those who got sick had milder symptoms6.
- Black garlic: Black garlic has more SAC than fresh garlic, but nearly all of its research is in cells and animals; human trials are few and small7.
If you want the dose behind these trials, look for 480–1,200 mg of aged garlic extract a day.
Who Should Skip It or Ask First
- Anyone taking warfarin, other blood thinners or daily aspirin: garlic may raise bleeding risk48.
- People taking HIV medicines (saquinavir, darunavir) or cyclosporine: garlic can lower their levels8.
- Anyone scheduled for surgery: stop garlic supplements 1–2 weeks before, as advised by your surgical team8.
- Anyone pregnant or breastfeeding: supplement doses haven’t been shown to be safe4.
- People on blood pressure medicine: AGE may add to its effect, so check your readings and tell your doctor.

The 6 Best Aged Garlic Extract Supplements, Reviewed
#1Best Overall
1. Kyolic Aged Garlic Extract Formula 100
BFN Score9.6/10
$$$Premium75 days (300 capsules)2 capsules twice a day
Strongest atEvidence fitWeakest atQuality & trust
Kyolic is made by Wakunaga, the company whose aged garlic extract was used in most clinical trials on AGE, including the 2018 blood pressure trial2. Four capsules a day give 1,200 mg of aged garlic extract powder, the same daily amount used in that trial.
Label Reality Check
- Active ingredient + form
- Kyolic aged garlic extract powder (bulb), organically grown garlic
- Dose per serving
- 2 capsules = 600 mg; directions say 2 capsules twice a day (1,200 mg)
- % DV / Upper Limit
- No DV or UL
- Purity testing
- IGEN Non-GMO Tested; no third-party potency seal
- Other ingredients
- whey, gelatin, magnesium stearate (vegetable source)
- Additives
- Clean
- Allergens & diet
- contains milk (whey); gelatin capsule, so not vegetarian
Clinical Relevance
Because the trials used this maker’s extract, Kyolic is the closest match to the research of any product we found. The label doesn’t state an SAC amount.
Strengths
- Same maker as the extract used in the blood pressure trials
- Label dose matches 1,200 mg a day
- Buyers say it’s odorless and easy on the stomach
Limitations
- Four capsules a day at the label dose
- Contains whey (milk) and gelatin
- The listing we checked was sold by a third-party reseller, so check the seller or buy from a pharmacy
Practical Details
Take 2 capsules with a meal, twice a day. Some people start with 2 capsules a day (600 mg), which is still above the 480 mg that worked in the 2013 trial1.
Best For / Not For
Best foradults who want the aged garlic extract with the most research behind it.
Not forpeople with milk allergy, vegetarians, or anyone on blood thinners without a doctor’s OK.
Buyer Experience
Buyers consistently praise the quality and say it has no garlic smell or taste. Many take it for blood pressure or cholesterol and report steadier home readings, and most say it doesn’t upset their stomach.
A smaller group notices no change, and a few report mild side effects.
vs. Micro Ingredients
Choose Kyolic for the research-matched extract and dose. Choose Micro Ingredients for a lower cost per day and fewer softgels.
Doctor’s Note
If you take blood pressure medicine, check your readings at home for the first few weeks; aged garlic can add to the drug’s effect.
Verdict: The aged garlic extract closest to the clinical research, at the dose used in trials.
#2Best Bulk Supply
2. Micro Ingredients Aged Odorless Garlic
BFN Score8.8/10
$$$Mid-range150 servings (300 softgels)2 softgels per serving
Strongest atPurity & additivesWeakest atEvidence fit
Micro Ingredients gives 500 mg of odorless aged garlic extract in two small softgels, with nothing added beyond the softgel shell. One pouch lasts five months, which keeps the cost per day low.
Label Reality Check
- Active ingredient + form
- odorless aged garlic extract (bulb), aged up to 24 months (brand claim), in softgels
- Dose per serving
- 2 softgels = 500 mg
- Dose vs. research
- Close to the 480 mg a day used in the 2013 trial, but a softgel extract rather than the Kyolic powder tested1
- % DV / Upper Limit
- No DV or UL
- Purity testing
- Made in a cGMP facility (brand claim); no third-party seal
- Other ingredients
- softgel (gelatin, glycerin, purified water)
- Additives
- Clean
- Allergens & diet
- no soy, dairy or gluten (brand claim); gelatin softgel
Clinical Relevance
The amount is in the range that lowered blood pressure in trials, but the label doesn’t state SAC, so it’s hard to compare directly with the research product.
Strengths
- Very short ingredient list
- 150 servings per pouch
- Small, easy-to-swallow softgels
Limitations
- No SAC amount on the label
- Many buyers report garlic burps or smell despite “odorless” on the label
- Gelatin softgel
Practical Details
Take 2 softgels a day with a meal. Taking them at the start of a meal or keeping the pouch in the fridge may help with garlic burps.
Best For / Not For
Best forpeople who want a long-lasting aged garlic softgel at a low cost per day.
Not foranyone very sensitive to garlic burps, or people avoiding gelatin.
Buyer Experience
Buyers like the quality, value and small softgels, and several say it helped their blood pressure or cholesterol.
The most common complaint is odor: many report garlic burps or a garlic smell, and some note stomach upset.
vs. Deal Supplement
Choose Micro Ingredients for a cleaner label with no added color. Choose Deal for the lowest cost per serving.
Doctor’s Note
If garlic burps bother you, try splitting the dose, one softgel with breakfast and one with dinner.
Verdict: A simple 500 mg aged garlic softgel that lasts five months; expect some garlic burps.
#3Best Black Garlic
3. Dr. Mercola Fermented Black Garlic
BFN Score8.7/10
$$$Premium90 servings (3 bottles, 180 capsules)2 capsules per serving
Strongest atPurity & additivesWeakest atValue & practicality
Dr. Mercola combines fermented black garlic powder with a concentrated black garlic extract and states the SAC on the label: 1.2 mg per serving. It’s the only product on our list that tells you how much SAC you’re getting.
Label Reality Check
- Active ingredient + form
- fermented black garlic bulb powder and fermented black garlic bulb extract
- Dose per serving
- 2 capsules = 692 mg powder + 120 mg extract, with 1.2 mg S-allyl cysteine
- Dose vs. research
- SAC equals the 1.2 mg in the 480 mg arm of the 2013 trial, but that trial used aged garlic extract, not black garlic17
- % DV / Upper Limit
- No DV or UL
- Purity testing
- SAC amount stated; no third-party seal
- Other ingredients
- hypromellose (plant capsule), organic rice hull
- Additives
- Clean
- Allergens & diet
- plant capsule; non-GMO, gluten-free and soy-free (brand claim)
Clinical Relevance
Black garlic is made by holding whole bulbs in heat and humidity for weeks, which turns them black and raises SAC7. Human evidence for black garlic supplements is still thin.
Strengths
- SAC stated on the label
- Plant capsule with no fillers
- Three-bottle pack lasts three months
Limitations
- Highest cost per day on our list
- Black garlic has less human research than aged garlic extract
- Some buyers notice a garlic smell or taste
Practical Details
Take 2 capsules a day with a meal.
Best For / Not For
Best forpeople who prefer black garlic and want a labeled SAC amount.
Not foranyone on a tight budget, or people who want the exact extract used in blood pressure trials.
Buyer Experience
Buyers say it’s effective and well made, and several use it for blood pressure or cholesterol.
Reactions to scent, taste and value are mixed, and a few report stomach upset.
vs. Nutricost
Choose Dr. Mercola for stated SAC and more garlic per serving. Choose Nutricost for one capsule a day at a much lower cost.
Doctor’s Note
If a product tells you its SAC, you can compare it with research doses; most garlic labels don’t.
Verdict: The most transparent black garlic we found, at a premium price.
#4Best Heart-Health Combo
4. Resilia Odorless Aged Garlic with CoQ10 & K2
BFN Score8.5/10
$$$Premium30 servings (60 softgels)2 softgels per serving
Strongest atPurity & additivesWeakest atEvidence fit
Resilia puts a 600 mg aged garlic blend, aged 20 months (brand claim), together with 50 mg of CoQ10 as ubiquinol and 180 mcg of vitamin K2 (MK-7) in two softgels. It’s the only combination formula on our list, and buyers rate it highly for having no garlic smell.
Label Reality Check
- Active ingredient + form
- aged garlic blend (deodorized garlic oil), coenzyme Q10 (as ubiquinol), vitamin K2 (as MK-7)
- Dose per serving
- 2 softgels = 600 mg garlic blend, 50 mg CoQ10, 180 mcg vitamin K2
- Dose vs. research
- Garlic amount is within the trial range, but as an oil blend rather than the extract powder tested12
- % DV / Upper Limit
- Vitamin K 150% DV; no UL set for vitamin K9
- Purity testing
- “Third-party tested” (brand claim, lab not named); GMP facility
- Other ingredients
- sunflower oil, gelatin (bovine), glycerin, purified water, beeswax
- Additives
- Clean
- Allergens & diet
- bovine gelatin softgel; gluten-free (brand claim)
Clinical Relevance
Vitamin K2 can make warfarin work less well, so this formula isn’t for people on warfarin9. CoQ10 is often taken by people on statins; see our guide to the best CoQ10 supplements.
Strengths
- Garlic, CoQ10 and K2 in one softgel
- Buyers rate it highly for no smell or aftertaste
- Two softgels a day
Limitations
- Garlic is an oil blend, not the extract used in trials, and SAC isn’t stated
- Vitamin K2 interacts with warfarin9
- 30 servings per bag, and buyers are split on value
Practical Details
Take 2 softgels a day with a meal; CoQ10 and K2 absorb better with some fat.
Best For / Not For
Best foradults who want one heart-focused softgel instead of three supplements.
Not foranyone on warfarin or other blood thinners, or people avoiding bovine gelatin.
Buyer Experience
Buyers say it’s effective, easy to swallow and has no garlic smell or taste. Many mention better blood pressure or cholesterol readings.
Opinions on value are split, and some notice no change.
vs. Kyolic
Choose Resilia if you also want CoQ10 and K2 in one pill. Choose Kyolic for the extract and dose used in the trials.
Doctor’s Note
Check your other supplements before adding this one; many multivitamins and statin “support” products already contain CoQ10 or vitamin K.
Verdict: A convenient three-in-one heart formula; skip it if you take warfarin.
#5Best One-a-Day
5. Nutricost Black Garlic Extract
BFN Score8.4/10
$$$Mid-range60 servings (60 capsules)1 capsule per serving
Strongest atValue & practicalityWeakest atEvidence fit
Nutricost gives 80 mg of a 25:1 black garlic extract (equal to 2,000 mg of black garlic, per the label) in one plant capsule a day. It’s the simplest routine on our list and the only vegan pick besides Dr. Mercola.
Label Reality Check
- Active ingredient + form
- black garlic extract 25:1 (bulb)
- Dose per serving
- 1 capsule = 80 mg extract (2,000 mg black garlic equivalent)
- Dose vs. research
- No human trial used this dose; SAC not stated7
- % DV / Upper Limit
- No DV or UL
- Purity testing
- made in an NSF-certified, GMP-compliant facility (brand claim); no third-party product seal

- rice flour, hypromellose (cellulose capsule), corn starch, microcrystalline cellulose, magnesium stearate (vegetable source), silica
- Additives
- Clean
- Allergens & diet
- vegan, gluten-free, non-GMO (brand claim)
Clinical Relevance
“Equivalent to 2,000 mg” describes the raw garlic used, not what’s in the capsule, and there’s no SAC amount to compare with research.
Strengths
- One capsule a day
- Vegan capsule
- Low cost per day
Limitations
- Smallest amount of garlic on our list
- No SAC stated
- Black garlic has limited human research
Practical Details
Take 1 capsule a day with food.
Best For / Not For
Best forpeople who want a simple, low-cost black garlic capsule.
Not foranyone looking for the dose used in blood pressure trials.
Buyer Experience
Buyers say it has no smell or aftertaste and value its price and simplicity. A few report better blood pressure readings, while others notice no difference.
vs. Dr. Mercola
Choose Nutricost for one capsule a day at a low cost. Choose Dr. Mercola for stated SAC and a larger dose.
Doctor’s Note
Extract ratios like 25:1 sound strong, but what matters is how much active compound you get; this label doesn’t say.
Verdict: The easiest black garlic routine, best seen as a light daily add-on.

6. Deal Supplement Odorless Aged Garlic – Lowest Cost per Serving
BFN Score8.2/10
$$$Budget250 servings (500 softgels)2 softgels per serving
Strongest atDose & safetyWeakest atQuality & trust
Deal Supplement gives 500 mg of odorless aged garlic extract in two softgels made with MCT oil, and one bottle lasts about eight months. It has the lowest cost per serving on our list.
Label Reality Check
- Active ingredient + form
- odorless aged garlic extract (bulb) in MCT oil softgels; aging time not stated on the label
- Dose per serving
- 2 softgels = 500 mg
- Dose vs. research
- Close to the 480 mg a day used in the 2013 trial, but a different form from the extract tested1
- % DV / Upper Limit
- No DV or UL
- Purity testing
- Made in a cGMP facility (brand claim); label carries a California Prop 65 warning for lead
- Other ingredients
- MCT oil (from coconut oil), softgel (gelatin, glycerin, added color, purified water)
- Additives
- Added color (type not named)
- Allergens & diet
- contains tree nut (coconut); gelatin softgel; no gluten, dairy or soy
Clinical Relevance
The milligram amount is in the trial range, but there’s no SAC on the label, and the Prop 65 lead warning means it isn’t our first choice for daily, long-term use.
Strengths
- Lowest cost per serving on our list
- 250 servings per bottle
- Small softgels
Limitations
- Prop 65 lead warning on the label
- Unnamed added color
- Many buyers report garlic smell and burps
Practical Details
Take 2 softgels a day with a meal.
Best For / Not For
Best forbudget-focused buyers who want a large bottle of aged garlic softgels.
Not forpregnant women, anyone sensitive to garlic burps, or people avoiding coconut or gelatin.
Buyer Experience
Buyers find the softgels easy to swallow, and several say they help with blood pressure.
Odor is the main complaint: many say the softgels smell strongly of garlic and cause burps. Opinions on quality and value are mixed.
vs. Micro Ingredients
Choose Deal for the lowest cost per serving. Choose Micro Ingredients for a shorter ingredient list with no added color or lead warning.
Doctor’s Note
A Prop 65 warning doesn’t mean a product is unsafe, but it’s a reason to prefer another option for long-term daily use.
Verdict: The cheapest way to take 500 mg of aged garlic a day, with trade-offs in odor and label transparency.
Products We Considered but Didn’t Include
Lunakai PRO Aged Garlic Extract 1,200 mg. A five-ingredient formula with too few buyer reviews to judge.
NatureBell Aged Garlic Extract 1,000 mg. Weak buyer feedback when we checked.
Micro Ingredients Odorless Aged Garlic & Black Garlic complex. Adds red yeast rice, which can contain monacolin K, the same compound as the statin lovastatin, plus nattokinase.
Swanson Aged Black Garlic. Only 30 capsules per bottle, and it overlaps with our two black garlic picks.
Nature’s Craft Odorless Garlic with Parsley, Zazzee Organic Garlic, Sports Research Odorless Garlic Oil and Nutricost Garlic 1,000 mg. All are regular garlic powder or garlic oil, not aged garlic extract; see our guide to the best odorless garlic supplements.

| Pregnancy or breastfeeding | Supplement doses not shown to be safe4 | Avoid unless your doctor advises |
How to Choose an Aged Garlic Supplement
Aged Garlic Extract or Not?
Look for “aged garlic extract” in the Supplement Facts, not only on the front. “Odorless garlic” often means regular garlic powder in a coated tablet or garlic oil, which is a different product.
Amount per Day
Aim for 480–1,200 mg of aged garlic extract a day, the range used in blood pressure trials12. Check whether the serving is one, two or four capsules.
Stated SAC
SAC is the best-studied compound in aged garlic. Few labels list it; when one does, about 1.2 mg a day matches the most effective dose in the 2013 trial1.
Extra Ingredients
Combination formulas can be convenient, but check each added ingredient against your medicines, especially vitamin K with warfarin and red yeast rice with statins.
Label Red Flags
- Garlic inside a proprietary blend without an amount
- “Equivalent to 5,000 mg” claims with no actual extract amount
- Red yeast rice or nattokinase added to a garlic formula
- Claims that garlic can replace blood pressure medicine
Important: These supplements are not intended to diagnose, treat, cure, or prevent any disease. Results vary by individual. If you have a health condition or take medications, check with your doctor before adding any new supplement to your routine.
Frequently Asked Questions
What is the best aged garlic extract supplement?
Kyolic Formula 100 is our top pick: it comes from the maker whose extract was used in the blood pressure trials, and the label dose gives 1,200 mg a day. For a lower cost per day, choose Micro Ingredients; for garlic with CoQ10 and K2, choose Resilia.
What is aged garlic good for?
What is aged odorless garlic?
It’s aged garlic extract, garlic soaked for many months until the strong-smelling compounds break down. It’s usually much milder than regular garlic, though some softgels in oil still cause garlic burps.
What is the best aged garlic for blood pressure?
Kyolic is the closest match to the trials, which used 480–1,200 mg of Kyolic extract a day12. Keep taking any prescribed medicine and check your readings at home. For more detail, see aged garlic extract for high blood pressure.
Is Resilia aged garlic any good?
Resilia is a well-rated combination formula: a 600 mg aged garlic blend with 50 mg CoQ10 and 180 mcg vitamin K2 in two softgels, and buyers praise its lack of smell. Its garlic is an oil blend rather than the extract used in trials, and its vitamin K2 makes it unsuitable for people on warfarin.
Is black garlic the same as aged garlic extract?
No. Both are aged, but black garlic is made with heat and humidity, while aged garlic extract is soaked in liquid for months. Black garlic has far less human research7.
How much aged garlic extract should I take a day?
Final Verdict
Kyolic Formula 100 is the best aged garlic extract for most people: it’s the closest match to the clinical research, at 1,200 mg a day.
For a lower cost per day, choose Micro Ingredients. If you prefer black garlic, Dr. Mercola is the only one that states its SAC. For garlic, CoQ10 and vitamin K2 in one softgel, choose Resilia, unless you take warfarin.
Aged garlic may help lower blood pressure a little over 12 weeks, but it doesn’t replace medicine, diet or exercise. Talk to your doctor first if you take blood thinners or blood pressure medicine.
